Renowned hardware leaker @kopite7kimi corrected their own prediction that Nvidia's next-generation flagship graphics processing unit based on the Blackwell architecture would feature a 512-bit memory interface. It will not. Nvidia's GPU, currently known as GB202, will apparently continue to use a 384-bit memory bus, but will adopt GDDR7 type of memory.
Nvidia's GB202 GPU is projected to feature up to 24,576 CUDA cores, a 33% increase over the number of CUDA cores packed in the AD102 GPU (18,432 CUDA cores). Rumors suggest the company will use one of TSMC's 3nm-class fabrication processes to make its GPUs based on the Blackwell architecture — though it remains to be seen whether Nvidia and TSMC will customize TSMC's 3nm-class nodes for GPUs, or if they'll stick to the default.
